Hallguards Farmhouse

Hallguards Farmhouse is a building that largely dates to the early 20th century, but incorporates an earlier core. This nucleus is part of a 17th-century wing that was originally attached to the now-demolished Old Hoddom Castle. Alterations were carried out in 1795 (marked by a dated lintel) and around 1860. The farmhouse consists of two rectangular blocks arranged in an irregular double-pile plan. The walls are largely harled, with red ashlar margins.

The east-facing elevation has three bays, with a bowed bay on the left that projects forward. A gabled entrance bay is set within this bowed section. The dressings used here include a door lintel dated 1795 on its underside, which was repurposed from the original front. The rest of the west block is set back to the right. The west-facing elevation has five bays (two bays plus three bays). The first two bays are bowed and contain three-light windows, likely dating back to 1795. Later, around 1860, these bays were raised, and some alterations were made, including a low-gabled wing added to the northwest. A narrow slit opening, measuring 5 inches by 13 inches, is located between the bowed bays, and is positioned beneath the stairs. The internal reveals are splayed and a doorway has been opened alongside this slit. A small wing dating to the late 19th century is attached to the north side. Sash windows are found throughout, and the roof features straight skews and corniced end stacks finished with slate.

The interior was renovated between 1892 and 1894. A large stone fireplace, featuring a plain, wide lintel supported by curved corbels, was exposed in the central hall in 1982. There is also a stone staircase and some decorative cornice plasterwork. The interior doors are panelled and set within architraves. The bowed bays are similar in design to those at Park Farm, Dumfries.

The garden contains a collection of interesting stones, including a large block that likely served as a door surround (presumably originating from Old Hoddom Castle), many cuboid ashlar blocks measuring 18 inches by 8 inches by 8 inches, and 15-inch square blocks with shallow diamond-pointing.
